What It Does

Every Chord In Key

Pick a key and scale. The seven chords that belong to it show up as rows, coloured by what they do: Home, Lift or Tension. One click or one number key plays one.

Piano And Guitar

Each chord is spelled on a keyboard and a fretboard, with voicings you can step through and inversions that follow the last chord.

Suggestions

Stuck? Borrowed and colour chords sit one row down, ready to try. Outside chords are marked so you know when you're leaving the key.

Progression Page

Assign a chord to each key or pad and play the song like an instrument. Every slot remembers its own voicing.

Built-In Synth

Oscillators, glide, four envelopes, a filter and distortion you can reorder. Enough to sketch without opening anything else.

MIDI And Humanize

Send chords to any synth or DAW. Strum, timing and velocity spread make it sound played, not pasted.
